Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cutting equipment, and in particular to a fiber laser cutting machine for processing steel structural parts. Background Art

[0002] Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. Fiber laser is a new type of fiber laser developed internationally that outputs a high-energy-density laser beam and focuses it on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to instantly melt and vaporize, thereby achieving automatic cutting. It is often used for cutting metal steel components.

[0003] When cutting steel components in the prior art, the steel components first need to be placed in the cutting position and fixed by a clamp, and then the position of the cutting device is adjusted and the cutting route is set for cutting. This process requires the use of precise instruments. When dealing with steel components of different sizes (including different lengths and widths), the cutting path and cutting position need to be repeatedly adjusted, which is inconvenient. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a fiber laser cutting machine for processing steel structural parts to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The limiting components on the four sides of the cutting plate can clamp and limit the side edges of the steel member at the same time. Two of the groups are connected to the cutting frame, corresponding to the route of the steel member to be cut, and the other two groups are squeezed and fixed on the top by a pressure plate. The laser cutting device cuts the steel member with the guidance of the cutting frame and the traction of the winding seat, and the cutting path is determined according to the length of the connecting rope, so there will be no problems of insufficient cutting distance or the cutting device moving too far.

[0006] Furthermore, side slide rails are provided on both sides of the cutting table, vertical beams are slidably installed on the side slide rails, the cross beams are slidably connected to the inner grooves of the vertical beams, a first electric push rod is fixed to the top of the vertical beam, and the extended end of the first electric push rod is fixedly connected to the cross beam.

[0007] Furthermore, a cylinder is fixed on the top of the slide, and the extended end of the cylinder is fixedly connected to the laser cutting device.

[0008] Furthermore, the surface of the cutting table is provided with sliding grooves at equal intervals, and a convex strip is fixed at a position corresponding to the sliding groove at the bottom of the cutting plate, and the convex strip is slidably inserted in the sliding groove.

[0009] Furthermore, the limiting assembly also includes a movable groove, the movable grooves are opened on the four sides of the cutting plate, and a translation screw is rotatably installed inside the movable groove through a bearing, a slide plate is threadedly sleeved on the surface of the translation screw rod, and a mounting frame is fixed on the top of the slide plate.

[0010] Furthermore, a bidirectional screw is rotatably installed inside the mounting frame through a bearing, and moving blocks are threadedly sleeved on both ends of the bidirectional screw. The moving block is rotatably connected to a connecting rod through a rotating shaft toward one side of the vertical plate, and the other end of the connecting rod is rotatably connected to the back side of the vertical plate through the rotating shaft.

[0011] Furthermore, a gear ring is rotatably installed on the periphery of the disc, the gear ring is fixedly connected to the rotating ring of the pressure plate, one side of the gear ring is meshingly connected with a gear, a driving motor is fixed on the top of the gear corresponding to the disc, and the output end of the driving motor is fixedly connected to the gear.

[0012] Furthermore, a second electric push rod is fixed to the top of the front end of the vertical plate, and the extended end of the second electric push rod slides through the disc and is fixedly connected to the connecting frame.

[0013] Furthermore, electric suction cups are fixedly installed on the top and bottom of both ends of the connecting frame, and the electric suction cups are adsorbed on the surface of the disc or the cutting frame under the push of the second electric push rod.

[0014] Furthermore, a screw column is fixed to the movable end of the connecting rope, a screw hole is provided at a position of the slide corresponding to the locking installation position of the connecting rope, and the screw column is threadedly inserted into the screw hole.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the gear to rotate and mesh with the gear ring through a driving motor, driving the pressure plate to rotate to the inner side of the vertical plate, that is, the upper end of the steel member, and then the electric suction cups of the connecting frames on the left and right sides are placed at the bottom of the disc to contact and adsorb and connect through the telescopic adjustment of the second electric push rod, and then the second electric push rod drives the pressure plate to press on the top surface of both sides of the steel member, and combines with the vertical plate to limit and clamp the left and right sides.

[0017] 2. The present invention rotates the bidirectional screw, the moving block engages with the bidirectional screw, and the connecting rod pushes the vertical plate to move until it contacts the steel structure. At this time, the front and rear end vertical plates slide along the groove of the cutting frame, and the connecting ropes of the front and rear end winding seats are connected to the screw holes of the slide through the screw columns, and then the translational screws inside the front and rear end moving grooves are driven to rotate separately, and the slide slides along the moving groove to adjust the lateral positions of the vertical plate and the cutting frame. Because of the connection between the slide and the connecting rope, the crossbeam now passes through the vertical beam along the side slide rail, keeping the path of the laser cutting device and the cutting frame in a straight line correspondence. The cutting frame squeezes and contacts the cutting sides of the top of the steel structure to avoid deformation caused by high temperature.

[0018] 3. The present invention uses a winding laser cutting device to synchronously slide along the crossbeam through the winding of the connecting rope. The movement of the laser cutting device is controlled by the winding seats at both ends of the cutting route, one for unwinding and the other for winding. Because the length of the connecting rope released by the winding seats at both ends is certain after adjusting the position, a servo motor controller is used to wind up the fixed length. When the length is reached, the winding is stopped immediately, and the slide and the laser cutting device also stop moving, thereby avoiding the problem of excessive movement of the laser cutting device or insufficient cutting.

[0019] 4. The cutting board of the present invention is slidably connected to the cutting table through the convex strips, and the cutting board can be pulled out from the cutting table by pulling, so as to facilitate the placement or removal of the cut steel components. In this process, the first electric push rod controls the horizontal beam to slide and rise along the groove of the vertical beam to avoid movement interference with the limit assembly on the cutting board.

[0020] 5. Compared with the prior art, the limiting components on the four sides of the cutting plate of the present invention can clamp and limit the side edges of the steel member at the same time. Two of the limiting components are connected to the cutting frame, corresponding to the route of the steel member that needs to be cut, and the other two groups are squeezed and fixed on the top by a pressure plate. The laser cutting device cuts the steel member with the guidance of the cutting frame and the traction of the winding seat, and the cutting path is determined by the length of the connecting rope, so there will be no problem of insufficient cutting distance or the cutting device moving too far.

In this solution, the cutting direction of the steel structure is limited to horizontal or vertical cutting. According to the two cutting directions, the corresponding cutting frame 23 is selected. Taking the figure of this solution as an example, the front and rear cutting direction is selected to cut the steel structure. First, the connecting frame 416 on the front and rear end vertical plates 45 is pushed by the second electric push rod 49 to contact the cutting frame 23. The two electric suction cups 417 at the bottom of the connecting frame 416 adsorb the cutting frame 23, and lift the cutting frame 23 from the storage groove 22 to facilitate the placement of the steel structure on the cutting board 2. The pressing plate 415 on the vertical plate 45 for connecting the cutting frame 23 is rotated to the back. After the steel structure 3 is placed, the vertical plates 45 on the left and right sides are The disc 411 drives the gear 414 to rotate and mesh with the gear ring 412 through the driving motor 413, driving the pressing plate 415 to rotate to the inner side of the vertical plate 45, that is, the upper end of the steel component 3, and then the electric suction cups 417 of the left and right connecting frames 416 are placed at the bottom of the disc 411 through the telescopic adjustment of the second electric push rod 49 to contact and adsorb and connect, and then the second electric push rod 49 drives the pressing plate 415 to press on the top surface of both sides of the steel component 3, and the left and right sides are limitedly clamped in combination with the vertical plate 45, and the front and rear and left and right vertical plates 45 are rotated by the two-way screw rod 42, the moving block 43 is meshed with the two-way screw rod 42, and the connecting rod 44 pushes the vertical plate 45 to move until it contacts the steel component 3. At this time, the vertical plates 45 at the front and rear ends slide along the grooves of the cutting frame 23.The connecting rope 418 of the front and rear end winding seats 410 is connected to the screw hole 420 of the slide 14 through the screw column 419, and then the translation screw rod 46 inside the front and rear end moving grooves 48 is driven to rotate separately, and the slide plate 47 slides along the moving groove 48 to adjust the lateral position of the vertical plate 45 and the cutting frame 23. Because the slide 14 is connected to the connecting rope 418, the crossbeam 13 now moves along the side slide rail 11 through the vertical beam 12, and the path of the laser cutting device 16 and the cutting frame 23 are kept in a straight line corresponding to each other. The cutting frame 23 squeezes and contacts the cutting sides of the top of the steel component 3 to avoid deformation caused by high temperature. When cutting in the left and right directions is required, the principle Similarly, the left and right vertical plates 45 are switched to connect with the cutting frame 23 to guide the laser cutting device 16. The winding laser cutting device 16 of the connecting rope 418 slides synchronously along the crossbeam 13. The movement of the laser cutting device 16 is controlled by the winding seats 410 at both ends of the cutting route, one unwinding and the other winding. Because the connecting rope 418 released by the winding seats 410 at both ends after adjusting the position is constant, the servo motor controller is used to wind up the fixed length. When the length is reached, the winding stops immediately, and the carriage 14 and the laser cutting device 16 also stop moving, which can avoid the problem of excessive movement or insufficient cutting of the laser cutting device 16.

[0034] When using the device, place the steel component 3 on the cutting plate 2, and clamp the four sides of the steel component 3 by the limiting assembly 4. According to the required cutting direction, connect the vertical plate 45 in the corresponding direction with the cutting frame 23, and cover the cutting frame 23 on the upper end of the steel component 3 to guide the laser cutting device 16. The winding seat 410 on the top of the vertical plate 45 pulls the laser cutting device 16 to make it cut the steel component 3 in a straight line. Select the front and rear cutting directions to cut the steel structure. First, the connecting frame 416 on the front and rear end vertical plates 45 is pushed by the second electric push rod 49 to contact the cutting frame 23. The two electric suction cups 417 at the bottom of the connecting frame 416 adsorb the cutting frame 23, and lift the cutting frame 23 from the storage slot 22 to facilitate the steel structure. The pressing plate 415 on the vertical plate 45 for connecting the cutting frame 23 is placed on the cutting plate 2, and is rotated to the back. After the steel component 3 is placed, the disc 411 on the vertical plates 45 on the left and right sides drives the gear 414 to rotate and mesh with the gear ring 412 through the driving motor 413, driving the pressing plate 415 to rotate to the inner side of the vertical plate 45, that is, the upper end of the steel component 3, and then the electric suction cup 417 of the connecting frame 416 on the left and right sides is placed at the bottom of the disc 411 through the telescopic adjustment of the second electric push rod 49 to contact and adsorb and connect, and then the pressing plate 415 is driven by the second electric push rod 49 to press on the top surface of both sides of the steel component 3, and the left and right sides are limitedly clamped in combination with the vertical plate 45. The front and rear and left and right vertical plates 45 are rotated by the bidirectional screw rod 42, and the moving block 43 is connected with the bidirectional screw rod 42. The connecting rod 44 engages with the screw rod 42, and the connecting rod 44 pushes the vertical plate 45 to move until it contacts the steel member 3. At this time, the vertical plates 45 at the front and rear ends slide along the grooves of the cutting frame 23, and the connecting ropes 418 of the front and rear end winding seats 410 are connected to the screw holes 420 of the slide 14 through the screw columns 419, and then the translation screw rods 46 inside the front and rear end moving grooves 48 are driven to rotate separately, and the slide plate 47 slides along the moving groove 48 to adjust the lateral positions of the vertical plates 45 and the cutting frame 23. Because the slide 14 is connected to the connecting rope 418, the crossbeam 13 now moves along the side slide rails 11 through the vertical beam 12, keeping the laser cutting device 16 and the path of the cutting frame 23 in a straight line corresponding to each other. The cutting frame 23 squeezes and contacts the cutting sides of the top of the steel member 3 to avoid deformation caused by high temperature. When cutting in the left and right directions is required, the principle is the same. The left and right vertical plates 45 are switched to connect with the cutting frame 23 to guide the laser cutting device 16. The winding laser cutting device 16 of the connecting rope 418 slides synchronously along the crossbeam 13. The movement of the laser cutting device 16 is controlled by the winding seats 410 at both ends of the cutting route, one unwinding and the other winding. Because the connecting rope 418 released by the winding seats 410 at both ends after adjusting the position is constant, the servo motor controller is used to wind up a fixed length. When the length is reached, the winding is stopped immediately, and the slide 14 and the laser cutting device 16 will also stop moving, which can avoid the problem of excessive movement or insufficient cutting of the laser cutting device 16. The cutting plate 2 is connected to the cutting table 1 through the convex strip 21.The cutting board 2 can be pulled out from the cutting table 1 by pulling, so as to place or take out the cut steel member 3. In this process, the first electric push rod 17 controls the horizontal beam 13 to slide and rise along the groove of the vertical beam 12, so as to avoid the movement interference of the limit assembly 4 on the cutting board 2.
